Finnish band combining the styles of humppa, a Finnish form of polka, with metal. Songs are sung in Swedish for the reason that it was the original singer's mother tongue, but also because it sounds "damn trollish".
They also have an obsession with trolls.

A two-man polka-metal band made up of two Finnish men, Vreth and Skrymer (real names unknown) with lyrics based on Scandinavian trolls, their first release being Ur Jordens Djup in 2007. Rumours of early demos featuring other members have circulated but no evidence appears to support this. When performing live they have a full backing band, who thus far have refused to be identified or photographed.

Fangirl 1: I love Finntroll so much!
Fangirl 2: Me too, Vreth is so hot!
Fangirl 3: I draw pictures of them having gay sex because I love folk metal.
